Parasite

In the year 1992 after a nuclear war has devastated most of the United States. Dr. Paul Dean (Robert Glaudini) develops a leech-like parasite that grows to large portions after it consumes the blood of its host. Paul flees to the desert when the government storms his lab to collect the parasites to use for their own purposes. He is pursued by "Wolf" (James Davidson) the "merchant" employed by the government to retrieve the last of the parasites. Paul carries one of the last parasites in a canister and the other inside of his stomach. He seeks refuge in small desert town populated by scavengers who constantly threaten his work. While most of the scavengers seek to rob him blind one woman Patrica Wells (Demi Moore) finds an interest in Paul and helps him to destroy the parasites before they multiply and devour the Earth's remaining population.
